Abstract :
A new GPR system, which uses an optical electric field sensor, was discussed. We proposed a new bistatic radar system, which is consisted of a TEM horn antenna as a transmitter and an optical sensor as a receiver. A broadband type optical sensor with a frequency bandwidth from 100MHz to 5GHz was applied to the land mine detection. Laboratory measurements showed that buried objects can be detected by the new GPR system. We found the difference of the reconstructed image dependent on the incident wave polarization.
